Calculus
The branch of mathematics that deals with the study of continuously changing quantities, with the use of limits and the differentiation and integration of functions of one or more variables, is called Calculus. Calculus analyzes aspects of change in processes or systems that can be modeled by functions. The English physicist, Isaac Newton, and the German mathematician, G. W. Leibniz, working independently, developed calculus during the 17th century.

How do you factorise 5x4 - 2x?
5x4 - 2x = x*(5x3 - 2) and that cannot be factorised further without invoking surds.
What is the difference between a 12mm x 1.25 and a 12mm x 1.5 auto nut?
The thread pitch is different. One is 1.25 threads per mm, and the other is 1.5 threads per mm.
What is the graph of the equation 2x2-6x plus 2y plus 18 equals 0?
2x2-6x+2y+18 = 0. Subtract the 2y from both sides. 2x2-6x+18 = -2y. Divide all by -2 to get y by itself. -x2+3x-9 = y. This graph is going to be a parabola that opens downward, like a frown.
What are the angles in a diamond?
There is no set rule establishing the angles on a diamond; even a square (all four corners 90•) turned on edge is a diamond. Generally, a diamond is considered to have two angles less than 90• and two angles greater than 90•, that's it.
Solve the equation -10 equals 12 plus x?
the answer is
-10 = 12 +x
x= -10-12
x=-22
this is the answer
x= -22
How do you find the derivative of 2xe-x?
f(x) = 2xe^-x
Apply the product rule.
f'(x) = 2 e^-x + 2x e^-x ( -1)
f'(x) = 2 e^-x - 2xe^-x
If y equals 53 degrees what is the complement of y?
The complement of an angle is the degree which makes the angle add up to 90 degrees. Therefore:
complement of y= 90-53
= 37.
The solution of the equation 5x equals 3x 13 falls between what 2 consecutive integers?
5x-2=13
+2 +2
5x=15
x=3
When the length of a pendulum increases what will it effect on the time period?
The period is proportional to the square root of the length so if you quadruple the length, the period will double.
5 + 7x = -23
1. First subtract both sides by 5 to isolate the variable x
So you get this
7x = -28
2. Divide both sides by 7 to get x by itself
x = -4
the answer is x = -4
2x-3y equals -1 y equals -4x plus 24?
2x - 3y = -1 Eq.1
y = -4x + 24 Eq.2
Put the value of Eq.2 on Eq.2
2x - 3(-4x + 24 ) = -1
2x + 12x -72 = -1
14x -72 = -1
14x = 72-1
14x = 71
x= 71/14 .............. X = 5.07
How do you factor x squared plus 16x minus 348?
x2 + 16x - 348 cannot be factored.
Solving for x with the quadratic formula results in x = -8 - 2√103 and x = -8 + 2√103
What is the inverse of yx5 x4 x?
Put simply, the inverse of y=x^5+x^4+x is x=y^5+y^4+y. Unfortunately, this is a quintic function and there is no quintic formula.
What high school courses do you have to take to be an architect?
You will need strong college prep courses. Math and physics are important. Language arts, history, computer drafting, and art, are helpful also.
classes like:
algebra
applied math (trig and stuff)
applied physics
arts
blueprint reading
college pre
computer science
drafting
english
geometry
graphic communications
history
industrrial arts
mathematics
mechanical drawing (or class that has it included, ask about that)
physics
trigonometry (of course)
What is cubic meter a measure of?
1000 litres.
The volume does not provide enough information to determine the shape: it could be a sphere, ellipsoid, cube, cuboid, other regular or irregular polyhedron, or simply a blobby shape! There is, therefore, no way to say anything about its dimensions.
What is 2xplus3 equals 9x equals?
2.33333 NO
subtract 2x from both sides so that the x's are all on one side and the numbers are all on the other, you should get 3=7x.
Then divide both sides by 7 to get the x by itself.
3/7= 2.333333
* * * * *
The correct answer is 0.428571... The earlier answer is correct all the way to the last step. 3/7 is not 2.33.. but 0.428571!
How do you solve 3 times 2 times 2 times 5x equals 60?
(3)(2)(2)5x=60
12(5x)=60
12(5x)/12=60/12
5x=5
x=1
What is one times one times one?
- The answer is one. You can break it up. One times one equals one and then one times one equals one! It's really simple for me to get the answer.
